SOLE-rename ATTACHMENT FOR SOLE-CUTTING MACHINES.

Application filed June 5,

Briefly, the invention consists of a fudg ingwheel mounted on the end of one of the knife shafts, beneath which is mounted a movable table to support the work, 'saidtable being normally disposed in front of the lower knife to act as a guard therefor, and being movable upwardly in cooperative relation with the fudgingv wheel whenthe operation of fudging is performed; p I

The, object of the invention is to provide a fudging attachment for a cutting machine in which one of the members of the fudging device performs its inherent function and at the same time guards the cutter knives, thus dispensing with the necessity for an independent fudgingmachine. A further object is to provide a fudging attachment including a knife guard that is simple and may be manufactured at practically the same cost as the old knife guard. Further and other advantages will be better apparent from a detailed description of the invention in connection with the accompanying drawings, in which Fig. 1 is a side elevation of a cutting machine provided with my fudging attachment; Fig. 2 is an end view thereof; and Fig. 3 is a vertical longitudinal section taken through the outer portion of the bearing for the upper knife shaft on the line 3-3 thereof showing the fudging wheel secured therto.

Referring to the drawings, 1 represents a supporting standard provided with a pair of shaft bearings 2, 2 in vertically spaced relation, the former receiving a shaft 3 and the latter a shaft 4, said shafts having a gear 5 and pinion 6 mounted on their respective right hand extremities, the shaft 4 having a crank handle 7 mounted on the outside of the pinion 6 whereby the shafts may be rotated simultaneously in opposite directions. A rotary cutting knife 8 is keyed to the left hand extremity of shaft 3, said knife cooperating with a rotary knife 9 securely fixed to the left hand end of shaft 4. The end of the bearing 2 is recessed at r to allow the knife 9 to fit inside the knife 8, and a bracket 10 is fixed to the outwardly 1926. 1 Serial no. 113,959.

projecting lug 11 forming the lower boundary of the recess 1". The bracket 10 is'bent from a piece of fiat metal into a substantially U-shape and is .secured to the outer face of the lug 11 by means of a stud 12 projecting therefrom and nut 13 screwed 'thereov'er. The parts of the machine thus far described are old and comprise a device for cutting sole leather, in the operation of which a table (not shown) is secured to the face of the lug 11 in lieu of the bracket lO, "said table projecting in front of the knife 9 and servesas a guard therefor as well as a support for the leather while being run between the knives 8 and 9 which obviously are rotated by turning the crank-7.

My improvement consists in replacing such guard as may be used to prevent acciden't'al contact with the knives with a fudging device which includes a vertically movable platen 14, said platen being in the shape of a disc and havlng a stem 15 pro ecting downwardly from it, said stem be- 1ng adapted to traverse openings 0 and 0 in the top and bottom members 16 and 17 respectively of the bracket 10. The extremity of the stem 15 is bifurcated, the slot 8 bemg adapted to receive the long arm of a lever 18 pivoted at 19 on the supporting member 1, the short arm 18 of said lever having a connecting rod 20 extending downwardly from its extremity to a pedal 21 pivotally mounted in a floor bracket 22. A link 23 is connected to the pedal 21 and a coiled spring 24 is connected between the link and the under side of the counter or bench B on which is mounted the supporting member 1 so that when the pedal 21 is depressed for the purpose of rocking the lever 18 to raise the table 14, the spring 24 will be expanded and when the pressure is released from the foot pedal 21, the spring 24 will bring the pedal 21 upwardly to its at rest position. The fudging device also includes a fudging wheel 25 mounted on the end of the shaft 3 outside of the cutter 8, said fudging wheel having a stem 26 projecting from its inner face, which stem is inserted in a socket 27 in the shaft 3 and securely held therein by a set screw 28. Obviously, when the crank 7 is rotated, the fudging wheel 25 will be rotated together with the shaft'3 and when it is desired to perform a fudging operation, the shoe S is placed upon the platen 14, the pedal 21 depressed so as to raise the platen and pinch the margin of the sole S between the platen andthe fudging wheel (as shown in dotted lines Fig. 1) after which the crank 7 is rotated while the sole is fed between the platen and fudging wheel.

It will be observed that when the platen 14 is in its normal or inoperative position, it is disposed in front of the knife 9 and owing to its size, projects beyond the knife when viewed from the position shown in Fig. 2 so that it serves to prevent accidental contact with the knife, thus guarding the operator from injury.

From the foregoing it is apparent that I have provided a fudging attachment for a sole cutting machine which in addition to performing its operations of fudging, has a member which serves as a guard for the knives of the cutting machine. Thus two machines are combined in one without substantially increasing either the size or the cost of the original machine.

Having described my invention, I claim:

1. A fudging attachment for a cutting machine having rotary vertically alined knives, including a wheel with suitable formations on its periphery disposed adjacent to the upper knife, a vertically movable table normally disposed adjacent the lower knife and movable into operative relation with the wheel, and means for rotating said wheel.

2. A fudging attachment for a cutting machine having a suitable supporting standard provided with a pair of vertically spaced bearings, a shaft disposed in each of said bearings, means for rotating said.

shafts, and a rotary knife mounted on the outer extremity of each shaft, comprising a fudging wheel mounted on the upper shaft outside the knife and in close relation thereto, a table movably mounted on said support, said table being normally disposed outside of and in close relation to the lower knife, and means for elevating said table into intimate cooperative relation with the fudging wheel.

3. A fudging attachment for a cutting machine having vertically alined rotary knives, including a fudging wheel disposed in front of the upper knife, a movable table disposed in front of the lower knife, a guide for said table, a stem depending from the table and traversing said guide, and pedal operated means for raising the table into operative relation with the fudging wheel to perform fudging operations.

In testimony whereof I hereunto aflix my signature.
